TUF 20 Episode 12 - The Ultimate Fighter: Pettis vs Melendez - Video

The biggest story of the semifinals might come down to the relationship shared between Esparza and Penne going into their bout. While Penne has made no secret all season long that she's a bit of a loner and shuts herself off to most people, Esparza happens to be one of the friends she's opened up to and remained close with throughout this entire process.

The two fighters also represent championship level talent, considering Esparza was the first ever Invicta FC strawweight champion while Penne was the former atomweight (105 pounds) champion. Esparza and Penne became good friends while serving as ambassadors for women's MMA and Invicta FC, probably thinking at the time that they'd never end up fighting each other since they were in different weight categories.
